It’s a tip I hear often and I don’t quite understand.
If the time is nearly up and you have to fill in answers for multiple choice, A,B,C,D for example. Why would you only go with ‘A’?
You should get around 25% of the answers correct but no proper test is ever going to have ‘A’ as correct answer many times in a row.
Would it not be marginally better to just pick at random?
Why not?
Edit: I understand real world is rarely truly random, but is my thinking here correct given answers are randomly distributed?

Provided the scattering is random, or at least random enough given the sample size, then there’s not actually a statistical advantage to picking one letter vs picking a scatter.
Only *slight* advantage at just filling in a single letter is it saves time guessing if you’re real short on time.
If you ever do this though make sure you understand all the grading rules, some tests deduct points for incorrect answers.
